摘要： Methods for integrating digital watermarks into holograms, watermarked hologram structures, and related applications. One method creates a watermark image, and then embeds the watermark image into a holographic structure. The holographic structure is created using computer generated holography to create a digital representation of the holographic structure. This digital representation is recorded on a physical substrate using optical techniques or microlithography. As an alterative, a watermark signal is embedded in a physical holographic structure by embedding the signal into an image that is optically merged with the holographic structure as it is optically recorded, or by embedding the signal into an image or physical model from which the holographic structure is formed. Another approach the creates a halftone watermarked image, and forms the halftone watermarked image in the hologram by creating hologram dots corresponding to the dots in the halftone watermarked image.

摘要： A method for examining the surface of an unwinding strip to detect a surface fault. The method includes forming at least a digital image of the strip having a set of image elements each with an assigned digital value. The digital image is filtered to detect surface defects. The filter digital image is processed to identify the type of surface fault in the strip. Before the digital image processing step, the digital image is segmented into doubtful zones each containing a surface defect with the image processing step being carried out on the doubtful zones.

摘要： An apparatus for currency discrimination comprises first and second stationary scanheads, disposed on opposite sides of a bill transport path, for scanning respective first and second opposing surfaces of a bill traveling along the bill transport path and for producing respective output signals. The bill travels along the transport path in the direction of a predetermined dimension of the bill. A memory stores master characteristic patterns corresponding to associated predetermined surfaces of a plurality of denominations of genuine bills. Sampling circuitry samples the output signals associated with the respective first and second opposing surfaces of the scanned bill. A signal processor is programmed to determine which one of the first and second opposing surfaces corresponds to the associated predetermined surfaces of the plurality of denominations of genuine bills. The processor then correlates the output signal associated with the one of the first and second opposing surfaces corresponding to the associated predetermined surfaces with the master characteristic patterns to identify the denomination of the scanned bill.

摘要： A fast semi-automatic prostate contouring method is provided using model-based initialization and an efficient Discrete Dynamic Contour (DDC) for boundary refinement. The user initiates the process of the preferred embodiment by identifying four (4) points on the prostate boundary, thereby scaling and shaping a prostate model, and then the final prostate contour is refined with a DDC. The method of the present invention has particular application during the pre-implant planning phase of a brachytherapy procedure. However, this method also has uses in any phase of dose planning in the brachytherapy procedure or any other therapy approach.

摘要： An image registration system and method employs a registration processor (130) to find an optimal registration of two volumetric images (110, 112) by finding a spatial orientation that optimizes the statistical measure cross-entropy. The cross-entropy can be minimized where one or more likely or reasonably good a priori estimations of the true joint probability density function (pdf) of voxel value pairs are available. Where such an estimate is not available, the joint pdf for one or more known incorrect spatial arrangements (e.g., based on prior misregistrations), can be used as the prior pdf estimate(s). Since the prior pdf estimate(s) are unlikely to be the true pdf, a spatial orientation maximizing the cross-entropy is found. Likely and unlikely prior pdf estimations can also be used together to register images. The transformation that optimizes the cross entropy provides an optimal registration, and the parameters for the optimized transform are output to memory (150) for use by a display system (160) in aligning the images for display as a fused or composite image.

摘要： The present invention comprises a novel method, system and device for post-processing images, such as trabecular bone images, obtained by MRI, CT, or other image technologies, to provide increasing apparent image resolution and to alleviate the effects of partial volume blurring, which otherwise precludes accurate measurement of structures in the limited-resolution regime in which image voxel size is larger than the typical structural element to be resolved. Since acquiring images at increased resolution often exacts an unacceptable signal-to-noise penalty, methods and systems to alleviate the adverse effects of partial volume blurring are instrumental for the accurate measurement of architectural parameters in applications, such as predicting the mechanical competence of trabecular bone networks. Referred to as “subvoxel processing,” the invention is applicable to volumes of interest containing material phases of two discrete signal intensities, and it has been shown to be significantly more accurate than trilinear interpolation in decreasing apparent voxel size, especially in the presence of noise.
